a)in a 33/11 kv transformer has more current on secondary.if
it is 33/.415 kv much more current in secondary .so
conductors on secondary should be designed to 415v ,and for
a large current.
But if it is 33/11kv transformer they will be distributed
to various 11/.415 kv transformers.so current capacity of
conductors are decreased.

What is highest size of HT motor like 11 kv or 33 kv,and how to make it 750 rpm.i think the size will be very big.any idea ? pl. reply..
